YOKE-FASTENER.

Original application filed February 29, 1912, Serial No. 680,665.

- 1913. Serial No. 772,539.

To all whom it may concern: I

Be it known that 1, CHARLES MURRAY, a citizen of the United States, and resident of Evanston, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Yoke-Fasteners, of which the following is a specification.

My invention relates to draft rigging and has particular reference to a novel connection between the draw-bar and yoke.

The subject matter of this application was first disclosed in my application Serial No. 680,665, filed Feb. 29, 1912.

It is well known that the connection between the draw-bar and the yoke is a point of weakness and many constructions have been devised whereby such connection may be strong and rigid and which construction shall eliminate the use of bolts or rivets, It is a common construction to rivet the yoke to the butt end of the draw-bar by means of two rivets. In practice, however, due to side strains, the rivets are very often sheared and the connection broken. One of the prolific causes of delays and accidents is the pulling out of the draw-bar due to a broken connection to the yoke.

. It is the object of my present invention to eliminate the possibility of such, contingencies and provide a connection whichshall be simple, easily applied and removed, which shall eliminate the use of bolts and rivets and which shall absolutely prevent the breaking of the connection between the Figure 1 is a side elevation showing a draw-bar, yoke and fastening means arranged 1n accordance with. my invention; Fig. 2 1s a. composite view showing the Specification of Letters Patent.

Divided and this application filed Jane draw-bar and yoke assembled and with the to fastening head ready to be slipped on; Fi

3 is a perspective View of the fastening hea and F ig. 4 is a perspective View of the two ends of the yoke.

Referring more particularly to the drawings it will be seen that the draw-bar shank?" 10 is provided with shoulders 11, with which. hooks 12, formed on the ends of the yoke 13, 11 may cooperate. Also formed on the ends of. the yoke are oppositely disposed hooks l h w The fastening head 15, is preferably in thef form of a rectangular casting having an.- opening therethrough of a size slightly' larger than the outside transverse dimen' sions of the yoke and arranged whereby the fhead may be slipped on over the yoke intoQ the position shown in Fig. 1. In this pos'i-. tion a key 16, is passed through registering apertures in the draw-bar and fastening head, which key is held in place by any suitable means such as the cotter 17.

One or more springs 18 are located within the yoke such springs abutting a front follower 19, as shown'in Fig. 1. On normal pull, the front follower 19 being held against movement, the spring will be compressed. On the rearward movement the arrangement may be such if desired, that the draw-bar fastening head and follower 19 may be moved rearwardly, the yoke remaining unmoved. In this instance the yoke will slide through the connecting means to the head.

It is obvious that othei' modifications maybe made in the construction shown and such modifications as are within the scope of my claim I consider within the spirit of my in-f vention.

I claim:

In a device of the character described, a yoke strap and means for connecting said strap toa draw-bar, said means consisting of a hollow head connected to the draw-bar and slidably connected with the yoke stlap by pull on the draw-bar.
